Carbochlorination of yttrium oxide

Thermochimica Acta, 2010
Abstract The reaction of chlorination of a mixture composed by Y 2 O 3 and sucrose carbon was studied by thermogravimetry over a temperature range of 550–950 °C. The reaction proceeds through several successive stages. The first of them is the formation of solid yttrium oxychloride (YOCl) and subsequently the YOCl is carbochlorinated to produce YCl ...

Electronic structure of yttrium oxide

Physical Review B, 1990
The electronic structure of stoichiometric Y{sub 2}O{sub 3} is studied both theoretically and experimentally. X-ray absorption, performed through total-yield measurements at the {ital K} and {ital L}{sub II} edges of yttrium atoms and the {ital K} edge of oxygen atoms, through total-yield measurements has given access to empty states of various orbital

Thin film studies of yttrium, yttrium hydrides and yttrium oxide

Journal of Physics F: Metal Physics, 1978
Electron diffraction work has been carried out on yttrium films prepared in a vacuum of 5*10-7 Torr during evaporation. The crystal structure of thin yttrium films (300 AA thick or less) is mainly face-centred-cubic with a0=5.25+or-0.05 AA which can be attributed to cubic yttrium dihydride.

Thermal transformation of yttrium hydroxides to yttrium oxides

Thermochimica Acta, 1988
Abstract The reaction between aqueous solutions of yttrium salts (chloride and nitrate) at constant concentration and alkaline solutions (sodium and ammonium hydroxides) were investigated under different conditions. As a result, amorphous and hexagonal yttrium hydroxides, Y(OH)3, were formed and in addition monoclinic yttrium hydroxide, α-Y(OH)3, was

Luminescence of yttrium oxide

Technical Physics, 2008
Pulsed cathodoluminescence of pure and neodymium-activated Y2O3 ceramic and materials used for its synthesis (commercial Y2O3 micropowder and nanopowder obtained from it by laser evaporation) is investigated in a wavelength range of 350–850 nm. In the micropowder, four series of narrow electron-vibration bands of intrinsic luminescence centers are ...
